Enhanced electric field and charge polarity modulate the microencapsulation and stability of electrosprayed probiotic cells ( ST44).

The effect of the polarity of the direct current electric field on the "organization" of (ST44) probiotic cells within electrosprayed maltodextrin microcapsules was investigated. The generated electrostatic forces between the negatively surface-charged probiotic cells and the applied negative polarity on the electrospray nozzle, allowed to control the location of the cells towards the core of the electrosprayed microcapsules. This "organization" of the cells increased the evaporation of the solvent (water) and successively the glass transition temperature (Tg) of the electrosprayed microcapsules.

Electrosprayed Ethyl Cellulose Core-Shell Microcapsules for the Encapsulation of Probiotics.

Electrosprayed ethyl cellulose core-shell microcapsules were produced for the encapsulation of probiotic subsp. (Bifido). Ethyl cellulose (ETC) was used as a shell material with different core compounds (concentrated Bifido, Bifido-maltodextrin and Bifido-glycerol).
